Abstract
This paper uses an National Association of Insurance Commissioners (NAIC) 1995 data set to examine the concentration of property and liability insurance by line of insurance in the U.S. The primary measure of concentration used is the Herfindahl index. The largest 100 affiliates are divided into three largest sets of 20, 30, and 50. We find that the homeowners line is the most concentrated line and commercial auto physical damage is the least concentrated line, with the top 20 affiliates commanding the largest between-set and within-set contributions.
